[Note to teachers and students: This Gizmo was designed as a follow-up to the Nuclear Decay Gizmo. We recommend doing that activity before trying this one. Vocabulary: chain reaction, CNO cycle, catalyst, deuterium, electron volt, fission, fusion, isotope, nuclear reaction, positron, positron emission, proton-proton chain Prior Knowledge Questions (Do these BEFORE using the Gizmo.) The chart to the right gives the isotope name, element name, number of protons, and number of neutrons of t...

IAEA definition of a nuclear weapon CORRECT ANSWER a device that releases explosive energy as a result of nuclear fission and fusion What is the appeal of nuclear weapons from a national security perspective? CORRECT ANSWER nuclear weapons deter military rivals from launching an attack on a state out of fear of reprisal; they give state military credibility Disarmament vs. Non-proliferation CORRECT ANSWER disarmament: the full eradication of nuclear weapons non-proliferation: aims to limi...

CEM 141 MSU Exam 3 Latest Update Graded A+ Ionization Energy energy required to remove an electron from an atom in the gas phase Left Side Electrons have weaker attractions to remove electrons *easier to remove electrons from the left side of the table than the right side* Does it take MORE or LESS energy to remove an electron from Li than from Na? MORE Why? Because as we move down a group, the orbitals become larger and weaker. While going across the effective nuclear charge in...
